-map 0 means add every input stream in to the output. You've said what
you want done with video, encode to prores_ks, and what to do with
audio, copy, you just need to either say don't add all streams (just
first video and all audio) or copy all input streams, including
metadata, and re-encode the video.
You can do both with -map, eg to not copy the metadata track: "-map
0:v -map 0:a -c:a copy -c:v prores_ks"
or to copy everything, but re-encode the video: "-map 0 -c copy -c:v prores_ks"
-c:v is an alias for -vcodec, -c:a for -acodec, in case you were wondering.
